'VALVE.

No. '866,906.1 specification of Letters Patent.

pplication filed January 29, 1907. I Serial No. 354,748.

To al# it may concern:

United4 States, residing at Mansfield, inthe county of Riehland andState of Ohio, have invented certain.

new ndluseul Improvements in Valves; and I do declare the following tobe? a full, clear, and exact description of the invention, 4suchas willenable others skilled in the art to use the same.

This invention relates to improvements in reciprocating val-veav whichit appertains to make and The obiect ofthe invention'is to provide avalv'e of this character,the construction or' which -affordsa rrn andtight engagement. with its seat when closed rhere-v 'i A further objectis to construct a valve seat in such With. the above `and other objectsin view, the invention consists of certain novel features ofconstruction, combination and arrangement of parts, as will behereinaiter described and claimed. 4

`In the accompanying drawings1-Figure l is a vertical sectional viewthrough a valve constructed in accordance with the invention; Fig. 2 isa horizontal sectional view on the line 2 2 of Fig. 1;` Fig. 3 is asimilar lview, taken on the line 3-3 of Fig. 1 and looking toward thelower side of the valve-seat; Fig. 4 is a detail, Vertical sectionalview through a portion of the valve and seat, showing the valve in anopen position. y p f Referring more particularly to the drawings, 1denotes the valve casing, which may be of any suitable form, but whichis here shown as an lordinary globe .valve casing. In the casing 1 isarranged avalve seat' 2, said sea-*comprising an outer annularbearingwall outer bearing wall .3. The lower portion of the outer bearingwall-3 and the lower'portion o the adjacent wall of the bearing ring 4are straight and parallel with each other, as shown at 7, while theupper portion of said walls flare or are inclined outwardly in oppositedirections, 'as shown at 8.

Adapted to be engaged with the seat,2 is a valve 9,

said valvebeing cup-shaped or provided on its lower side with adepending annular flange 10. The innerV and-outer walls of the lowerportion or' the flange l1Q are straight and parallel with each other, asVshown at 1.2, while the upper portions ofthe flange are provided withoutwardly'tlaring o'r inclined walls 13. When l l the valve is eng-gedwith its seat.. the straight lower Beit ln'iown that I, JOHN H. BERRY, acitizen of the the outer bearing wall 3 of the seat` while the upper 60voutwardly-dared portion of the a'ngc l0 will engage the outwardly flaredor inclfinedportions 8 .of saith bearing walls of the seat, thusproviding for a firm and tight engagement between ,fthe valve and itsseat.

- The inclined portions of the' walls of the seat will 65 facilitate theremovel and discharge of any accumulations of refuse by the flange 10ot' the valve when `*engaged therewith, thuspreventing the clogging of v`the valve or interfering with the operation 'of the same.

In thc uppcr portion of the valve is formed an intcriorlythreadedannular recess in which is adapted to .be swiveled the lower anged endof a valve stem 14. This stem 14 is' secured in'swivelecl engagementwith the valve by'nreans of a flangedexteriorly-threuiL l ed sleeve l5,which is screwed into the threaded recess of the valve and into`engagement with the fiange on the inner end of the valve stem, asshown. The

stem 14 is provided with coarse operating threads 15, which are adaptedt0 be engaged with an interior-lythrcaded sleeve or cylinder lo formedon the cap 17,

which is screwed into the upper open end of the valve casing, as shown.The upper end of the sleeve' 16'is provided with a packing gland 18,through which the stem 14 works. The-upper end of the stem 14 is hereshown as being provided with a hand-wheel 19, by

means ol' which the same is screwed inwardly or outwardly to close oropen the valve. y

A valve constructed as herein shown and described vmay be employed inany capacity where a valve of this character may be used, the same,however, being especially constructed for use as a blow-of-valve l'orsteam-boilers.

From the foregoing description, taken inconnection with theaccompanyingdrawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes-in the form. proportion and the minor details ofconstruction may be resorted tio-with? out departing .from the'principleor sacrificing any of 100 the advantages of thislinvention, as defined.by the appended claims. A

Having thus described my invention, what I claim as new and desire tosecure by` Letters-Patent, is:-

1.The eombinatlionvof a. valve easing, a seat formed 195 and having adepending' ange to enter the channel bef 110' l `tween the spaced walls.y i

2.('1he` combination with a valve casing, of a seat tornietl therein andcomprising a pair of spaced continuous valveseat, and' the walls havingparallel lower portionsl walls provided with connecting lugs, said lugsbeing spaced relatively to provide discharge openings leading from theand beveled upper portions, a valve arranged to close on said seat andhaving a depending flange Ato seat between said walls, said flangehaving the low'erportion of its inner and outer faces parallel and theupper portion of said faces divergently inclined to conform to thebeveled portions of the walls, and means for operating the valve.

3. The combination, with a valve casing, of a seat formed therein, saidseat comprising an outer annular bearing wall and an inner bearing ringspaced from said outer bearing wall to form an annular space or channel,integral lugs. to Yconnect said inner ring with the outer an- .'nularwall of the seat, said lugs forming openings. or

spaces between themselves for the discharge of refuse, and

a valve adapted to be engaged with said seat, substan` tially asdescribed.

4. The combination with a valve casing, of a seat formed therein, saidseat comprising an outer annular bearing wall and an inner bearing ringspaced from said -outer bearing Wall to form an annular space 0rchannel,

integral lugsto connect said inner ring with the outer annular wall ofthe seat, said lugs 'forming openings or lspaces between themselves forthe discharge of refuse, and a valve having an annular bearing flangeadapted to be engaged with said inner bearing ring and outer bearingwall, substantially as described. 1 y..

5. The combination with a valve casing, ofa seat formed therein, saidseat comprising an outer annular bearing wall and an inner bearing ringspaced from said outer bearing wall 'to form an annular space orchannel, the upper portion of said outer bearing wail and the adjacentwall oi said bearing ring being beveled or dared outwardly and havingparallel, perpendicular lower walls, integral spacing lugs to connectsaid inner ring with 4the outer annular wall of the seat, said lugsforming discharge openings between said parts oi.' the seat, and a valveadapted to be engaged with the latter, substantially as described.

6. The combination with a valve casing, of a seat formed therein, saidseat comprising an 'outer annular hearing wall and an inner bearing ringspaced from said outer bearing wall to form an annular space or channel,the upper portion of said outer bearing wall and the adjacent wall ofsaid bearing ring being beveled or dared outwardly and having parallel,perpendicular lower walls, lntegral spacing lugs to connect said innerring with the outer annular wall of the scat, said lugs formingdischarge openings between said parts of the seat, and a valve having`an annular bearing flange, the inner and outer walls of the lower endof which arestraight and parallel, said walls iiaring outwardly towardthe upper end of the valve, substantially as described.

In testimony whereof -I have hereunto set my hand in presence of twosubscribing witnesses.
